Safe airport operations also include a fail-safe power supply. In order to be well prepared for power outages, Düsseldorf Airport will be using the FREQCON BESS EV battery energy storage system with second-life vehicle batteries from Mercedes-Benz Energy with a capacity of 1.4 MWh from next year on. FREQCON GmbH will supply the storage unit together with its multi-source converter with an output of 1.5 MW as an in-house solution and install the system in the existing operating room. On the one hand, the storage facility is to serve as a back-up system for securing the power supply of an office section in Hall 8 above the storage facility, and on the other hand, it is to supply primary control reserve.
Due to comprehensive safety and fire protection requirements, Düsseldorf Airport relies on the use of vehicle batteries. BESS EV is a highly safe and reliable energy storage solution. Closed housings and integrated exhaust air ducts ensure a high level of fire safety for the storage unit. The battery management system monitors and protects all battery modules and shuts down individual modules in the event of a fault.
